Settings

Device Settings

Input Device:

Test the selected input device to ensure it works properly.

Recording Settings

Noise Threshold:

0.11

Threshold for auto-trigger. Higher values require louder noise to start recording.

Recording Duration (seconds):

60 seconds

Maximum recording time per trigger. Recording stops automatically after this time or when noise drops below threshold.

Manual Recording Duration (minutes):

120 minutes

Maximum duration for manually triggered recordings. Recording stops after this time or when manually stopped (1 to 240 minutes).

Auto Recording: Enable or disable automatic recording based on noise threshold. Manual recording is always available.

Noise Filter Consecutive Chunks: Number of consecutive audio chunks that must exceed the threshold to trigger recording. Helps filter random noises (1-20).

Recording Format: WAV is lossless but larger files. MP3 is compressed and smaller.

MP3 Bitrate (kbps): Bitrate for MP3 compression. Lower values save more space but reduce quality.

Advanced Noise Filtering

Warning: Changes to these noise filters require a full application restart to take effect.

Noise Gate: Automatically mute low-level background noise below threshold

Adaptive Noise Reduction: Learn and remove consistent background noise patterns

High-pass Filter: Remove low-frequency rumble and wind noise

De-essing: Reduce harsh S sounds and plosives

Notification Settings

Enable Gotify Notifications: Enable or disable sending notifications via Gotify.

Gotify Server URL: URL of your Gotify server (e.g., http://192.168.88.17:8090)

Gotify API Token: API token for sending notifications

Notification Priority: Priority level (0-10, higher = more important)

Notification Title: Title for recording notifications

Test Gotify Notification: Test the Gotify notification setup.

Voice Filtering

Enable Voice Filter: Apply bandpass filter to focus on human voice frequencies (100-4000Hz by default). Reduces background noise.

Low Frequency Cutoff (Hz): Lower frequency cutoff for voice filter (20-500Hz). Default 100Hz removes low-frequency noise.

High Frequency Cutoff (Hz): Upper frequency cutoff for voice filter (1000-8000Hz). Default 4000Hz removes high-frequency hiss.

Filter Order: Filter steepness/order (1-10). Higher values give sharper cutoff but may cause artifacts. Default 4.

Extension & Playback

Extension Window:

5.0 seconds

Time window to check for noise when deciding to extend recording. Higher values tolerate longer pauses.

Audio Chart Size: Size of the live audio signal chart on the main page.

Chart Amplitude Max:

0.1

Maximum amplitude level for the live audio signal chart (0.1 to 1.0).

Microphone Controls

Analog Gain

Capture Volume:

N/A

Main analog gain for microphone input (0-100%). Adjusts overall sensitivity.

Mic Boost:

N/A

Pre-amplifier boost for external mics (0-3 levels, ~0-30dB). Increases low-signal gain.

Internal Mic Boost:

N/A

Boost for built-in microphone (0-3 levels). Only available on devices with internal mic.

Digital Gain

Digital Capture Volume:

N/A

Digital gain for USB/digital mics (0-100%). Applied after analog conversion.

Monitoring

Mic Playback Volume:

N/A

Volume for mic monitoring through speakers (0-100%). Lets you hear your own voice.

Mic Playback Switch: Enable/disable mic monitoring (sidetone). Routes mic input to speakers for testing.

Mute

Capture Switch: Enable/disable microphone capture. Mutes mic input for privacy or troubleshooting.

UI & Display

Theme: Visual theme for the application.
